In an automotive speed control device in which an accelerator pedal is held in a decelerating position by a force produced by an operating fluid pressure which is proportional to a predetermined speed setting, a relief means in the form of a spiral spring or a pressure relief valve is provided to absorb or relieve a strong depressing force exerted by a vehicle operator to the accelerator pedal. The speed control device further comprises a release means by which the operating fluid pressure is released in accordance with a release signal.
